It's been 2 days and approx 20 hours use, without a drop. I've looked to this thread multiples times since I HAD (hopefully) the same issue. Brand new Samsung Series 5 Ultra Notebook Windows 8 with the Intel Centrino Advanced-N 6235 wireless adapter. Frequent "Limited" status and drop of my personal wifi network, that required a disconnect from the network (the only one listed even though others were available) and an internet access icon right click and walk thru Troubleshoot Problems. Then all networks showed as available and I could connect again. Until the next drop. Two days ago I used SW Update which did a BIOS update, among other updates. (That was an issue for another thread, but I digress.) Then I went into Device Manager, Network Adapters, found Intel Centrino Advanced-N 6235 right clicked it, chose Properties and I clicked the Driver tab, checked that my driver issue is 10/31/13 15.10.5.1, and then clicked the Power Management tab where I found that the box was checked to "Allow computer to turn off this device to save power." I unchecked this box and saved the changes. I hope I am not premature in thinking my issue is resolved, but one or more of the above seems to have stopped my frequent drops.
